What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundDue to their versatility, mechanical strength, and biocompatibility, polyetheretherketone (PEEK) and its composite form have attracted a lot of attention for biomedical applications. However, creating long-lasting adhesion between PEEK and titanium remains a significant difficulty, particularly for implants and prostheses. Although surface treatments and bonding techniques have been studied for better interfacial adhesion, it is unclear how effective they are in comparison.
methodsUsing various surface preparation and bonding processes, a systematic study was conducted to evaluate the adhesion strength of glass-reinforced PEEK bonded with titanium and pure PEEK. Surface preparation methods, bonding agents, adhesion strength (MPa), and failure mechanisms were investigated using a combination of experimental and in vitro investigations. The effectiveness of certain treatments, such as laser structuring, air-particle abrasion, and chemical alterations, was compared statistically.
resultsIn contrast to air-particle abrasion, which produced shear bond strength gains of 0.4 MPa and significantly higher values when combined with bonding agents, laser structuring improved adhesion strength by up to 300% over untreated surfaces, according to the 10 studies that made up the review. The adhesion properties of glass-fiber-reinforced PEEK were superior to those of clean PEEK, particularly when combined with acid etching or plasma spraying. Microscopic investigations revealed improved mechanical interlocking and interfacial contacts, with adhesive and mixed failure modes predominating. Better durability was shown by thermocycling techniques; samples that were cycled 5000-1,200,000 times demonstrated increased adhesive strength in simulated environments.
conclusionThis study demonstrated that surface treatment techniques, particularly air-particle abrasion and laser structuring, significantly increased the adhesion strength between titanium and PEEK and glass-reinforced PEEK. Potential treatment approaches were suggested since high-performance bonding agents also promoted long-term interfacial adhesion. However, standardisation is necessary to improve comparability due to variations in methodology among research.
